Your child’s digestive system is similar to a processing plant – its main function is to convert food into energy and nutrients the body needs.

The entire process of digestion starts right in the mouth (saliva starts the digestive process off), and this process will continue as the food/drink passes through the digestive organs (e.g. stomach, small intestines and large intestines).
